Cockscomb cultivation techniques.

Climatic soils. Prefer warm climates. The soil requirements are not strict, but it is better to cultivate with well-drained sandy soil.

Planting. Seed propagation. General live broadcasting, seedlings can also be transplanted.

During the live broadcast, 5-6 taels of seeds per mu, mixed with the fire ash mixed with human and animal manure water, open the hole according to the row, plant spacing about 30cm on the furrow, about 3cm deep, the bottom of the hole should be flat, first apply human and animal manure water, and then evenly spread the seed ash.

Field management. When the seedling height is 7-10cm, the seedlings are evenly balanced, the seedlings are supplemented, and 4-5 strong seedlings are left in each hole. Weeding and top dressing, the first time is carried out after the acre is even, and the second time is in May. Water when there is a drought.

Harvesting and processing.

Generally, before and after the white dew, the seeds gradually black and mature, the flowers and moss can be cut off in time, put in a ventilated place to dry and thresh, the flowers and seeds are managed separately, and they are respectively medicated, and the seeds per mu are generally 300 kilograms, and the flowers are about 1000 kilograms. Flowers should go out early and return late when drying, do not make night dew, so as not to deteriorate and reduce the efficacy, the seeds should be cleaned, bagged and stored, and mildew and insects should be prevented.

Manage conservation. It is planted in high, dry, sunny, fertile, well-drained sandy loam soil.

Do not water too much during the growing season, control watering after flowering, water properly when the weather is dry, and drain water in time on rainy days.

Remove all axillary buds from the seedling stage.

After the cockscomb is formed, apply 1 thin [Banedabica] water-soluble fertilizer (2 3 times) every 10 days.

Leaf wilting is generally caused by 3 reasons, the first is insufficient watering, which is the most common cause, the second is caused by excessive watering and poor breathing of the root system, and the third is due to fungal infection.

Causes disease, resulting in leaf wilting.

In the high temperature and high humidity season, attention should be paid to drainage and ventilation, to prevent soil splashing on the leaves when watering, and not to drench on the leaf surface when watering, so as to reduce the disease conditions.

Be sure to water more than you want, and don't keep it in the sun all the time!

In general, the curling leaves of plants are subject to aphid insect infestations, and the main characteristics of the manifestation form are that the leaves are curled and the new shoots do not stretch.

The following is excerpted from the web:

Hazard performance: The aphids that harm cockscomb flowers are mainly bean aphids. It gathers in the new shoots, young leaves, petals and other places of the cockscomb to suck the juice, affecting the elongation of new shoots and new leaves, and causing the flower buds to fall off.

Bean aphid is also known as Shouqing aphid. Wingless viviparous females are broadly oval, 1 5 mm long, black-brown to brownish-green. Winged viviparous females are ovate, about 2 mm long, and blackish-brown.

The nymphs are covered with white wax powder. Bean aphids occur in East China for more than 10 generations in one year.

Control measures: Control measures for cockscomb aphids: First, when a small number of potted cockscomb aphids occur in the family, they can be brushed off and killed with a brush to wake up the water, or they can be sprayed with tobacco water (1 part of tobacco leaves is added to 40 50 parts of water; After soaking for 1 day and night, it can be used by rubbing and filtering).

The second is the prevention and treatment of pesticides. It can be sprayed with 50 pine borer emulsifiable concentrate 1000 times or 20 pyrethrin season oil 2000 2500 times and 80 dichlorvos emulsifiable concentrate 1500 2000 times during the aphid damage period.

The leaves of the cockscomb are not curly, the leaves are because of leaf curl disease, and they need to be sprayed with a certain amount of soda water.

Last year, I had it, and it would be nice to take the formula two or three times.

There are many possibilities for cockscomb leaves to roll.

If it is caused by transplanting too late, it is necessary to prune the branches and leaves properly to accumulate nutrients for root recovery; If the temperature is too low, you need to put it in a warm place;

If the soil is dry, it needs to be hydrated; If the light is too strong, you need to move it to a cool place to recover, and then receive light, but avoid strong light exposure.

First, the breeding method of cockscomb.

1. Soil. The cockscomb flower is not strict for the environment, but it is cultivated in well-drained sandy soil, and if the drainage is not good, the cockscomb is susceptible to root rot.

2. Watering. Cockscomb flowers should not be watered too much during the growth period, and watering should be controlled after flowering, proper watering when the weather is dry, and timely drainage on rainy days.

3. Fertilization. From the seedling stage, all axillary buds should be removed, and after the formation of the cockscomb, the water-soluble fertilizer of fertile leaf amino acids should be applied once every 10 days.

4. Illumination. Cockscomb prefers warm climates, likes sunshine and avoids cold. If it grows in the shade, the inflorescence is small, the ornamental value is reduced, and the suitable growth temperature is 18 -28. Growth is slow at low temperatures, and plants die in winter.

1. Symptoms of dehydration. Be watered promptly.

2. Deficiency symptoms, to supplement the missing elements in time, there may be a lack of potassium here, it is recommended to loosen the soil with some grass ash or sea food wogao potassium flush fertilizer dilution use.

3. Symptoms of pests and diseases, foliar spraying, and carefully check whether there are aphids on the back of the leaves.

This is cockscomb powdery mildew, which is a fungal disease, which can be prevented and controlled with pesticide powder, and the effect is better.
